for me the biggest limitation of gr07 (the first version) is in PRAT. the phones are just not fast enough to be engaging over a long period of listen.

It's slow tempo doesn't seem like an issue since it has an excellent instrument separation (I always though this was the function of transient speed [hence prat] but I guess other factors do affect instrument separation since gr07 does this better than some other phones that sound faster) but moving over to my speakers or even akg271, it's quickly revealed just how slow these phones are. anyone have similar experience with newer versions?

lolwut??

The GR07 is one of the fastest dynamic driver based phones you can get. Maybe you're confusing a lack of very bright treble for speed.

Here, use this video as a test for speed. It gets real fast at around 2:30, and only gets even faster from there. Most headphones simply gloss over a lot of notes. My HD600 isn't nearly as fast as the GR07, and misses so many notes. Compare your speakers and K271 to the 07, and then get back to me.

didn't i already imply that i compared them? and would i be making such an observation without doing so? why don't you try listening to my gr07, my akg271 and my 3 way setup with myrefc amps through my ears before getting back to me? you shouldn't be so quick to shun someone else's opinion just because they differ with yours. and fiy, hd600 is also not a very fast can.

You're right. Maybe our definitions of "slow" are different.

What exactly are you referring to when you say that it's slow? Does it gloss over notes? Does it miss details in the recording because the song is too fast? Is the note attack not there?

BTW, I've listened to the K271, among at least 20 other top tier iems. The result has always been the same. The GR07 is faster than most.

While I agree that the GR07 wasn't my number one choice for toe tapping engagement or as you might say PRaT, but I don't exactly agree that it has anything to do with speed. And like eke, I'm a little surprised that you find it slow. It's not the fastest I've heard but to call it slow is a little bit misleading, especially when saying its the cause of something that a lot of factors weigh in on, one of the least of which, is sheer speed or the resolving nature of an IEM. I think PRaT might be more related to the ratio of Attack to Decay speed and intensity across the spectrum.

Tom actually put me onto an interesting little test of speed in Good Feeling by Flo Rida, which would surprise you going from a slow to a quick IEM.

Personally, I use Avant, Ren Dez-Vous from the Rahxephon OST (video below) in addition to Good Feeling to get a sense of speed, but I also use this this track to feel out instrument separation and to a smaller extent layering.

If memory serves, this is a track the GR07 stumbled on just a bit. It sounds like a mess at first but it really makes sense in the show's context. Having the track in better quality obviously helps with this sort of thing.

Edit:

For what it's worth, my ASG-1 has it's own problems with this one too.

As much as I love Versailles, is this the only song you tested with? Versailles has a style that goes from slow symphonic to speed metal which creates an illusion that they do speed metal which they don't. You may want to find a other bands that moves fast for the whole song and hear the differences in tempo there. Versailles only plays fast for 1-1.5 min then goes away for most if the time. Try bands that plays fast for the full 5-6 mins.

That's a fantastic track V. I'll be using it from now on when I test iems.

Ahm it sort of does, that particular song only has one climax and it happens to be the fastest. Now what happens if a different band play at the same fast speed as that songs' climax multiple times through out a song but with slightly different speeds? The song would sound like it's being played at one speed and wouldn't take note of the speed changes.

Well maybe I am too critical of these iem, or I have been too spoiled by open headphones. The difference is just so large that metal isn't as impressive in these as I expected.

I'm a bit confused. It sounds like you're saying that the fast parts of the song are no longer fast, due to the fact that some parts are slow?

When I say fast, I'm referring to the speed of the drums, guitar, etc 3 minutes into the song.

What open headphones are you referring to?

I am saying if a band plays the fast segment similar to the one in Silent Knight multiple times through out a song with slightly different speeds, then the change in speeds are hardly noticeable. I can hear this difference is what I am saying.

And yes for metal, we are almost always referring to guitar and drums.... and /or keyboards if you listen to power metal.

I use Shure 1840 and HE-500

Interesting. I wouldn't classify the HE-500 as a "fast" headphone either.

yea, nope, one of the reasons why I am still unimpressed with it also but I am holding my doubts until I get a stronger amp. One I heard in a meet sounded really great and I actually think it can finally hang with the Shures. I mostly use the Shures.

Ok, I haven't heard the Shure so I don't know your frame of reference.

Maybe, from what I've read about the Shure, something from Etymotic (likely the HF3) will suit you better.

Ok. Just ordered the GR07 MKII's from Amazon via Quantum Wireless. Hopefully no surprises this time. Anyone else order from them?

I did, and it was missing the hard case. It was wrapped in plastic that was all scratched up and the box looked old, like as if they were sitting in the warehouse for years. The GR07s themselves looked unused, though... and nothing else was missing.

I looked back at some of that seller's reviews the other day after I left my review and someone else had the same problem with the exact same headphones.

Luckily, it was fulfilled by Amazon and they issued me a partial refund. They offered me to return the item but I fell in love with them right away... therefore, the reason for a partial refund (which was rather generous for just a missing case)

Edit:I forgot to mention that I noticed (after my incident) they weren't selling the GR07, anymore, until just a couple days ago. Hopefully, Amazon notified them and shipped their batch of GR07s back in return for some new ones.

Edit: Also, I am eager to hear your feedback on comparing the MK2 with the MK2 BE. I was contemplating on which to purchase when I got mine and picked the original MK2 because of the amazing bass boost (when needed) on my E12.
